Google unveils Google Assistant, a virtual assistant that's a big upgrade to Google Now

Google today said it was unveiling a virtual assistant tool at its annual Google I/O developer conference in Mountain View called Google Assistant. This appears to be similar to what Google Now can do already, but it appears to be an upgraded version of it. You can ask a question for an answer, and follow up with multiple questions, with Google picking the conversation out and returning the right answer. The service is integrated in its new conversational user interface products: Google Assistant is also built into Allo, its new independent chat bot app, as well as Google Home, its Amazon Echo competitor. "Think of the assistant, we think of it as a conversational assistant, we want users to have an ongoing two-way dialog," CEO Sundar Pichai said.
